PLUG FOR WATER AND STEAM COCKS.

SPECIFICATION forming part Of Letters Patent N 0. 698,007, dated April22, 1902.

Application filed July 31,1901. Serial No. 70.384- (No model.)

To to whom it may concern.-

Be it known that I, ISAAC N. GLAUBER, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Plugs for Water andSteam Cocks; andI do declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to improvements in plugs for water and steam cocks;and theinvention consists in the construction and combinations of theplug, substantially as shown and described, and particularly pointed outin the claims.

Figure 1 is a perspective view of my improved plug apart from othermechanism. Fig. 2 is a side elevation of a coupling and of the plugseated therein. Fig. 3 is a sectional elevation of coupling and pluglengthwise of the coupling. Fig. 4: is a perspective top View of thecoupling alone; and Fig. 5 is a cross-section on line A A, Fig; 2. Fig.6 is a horizontal cross-section on line B B, Fig. 2.

As thus shown and described, the plug A in itself, apart from itsspecial features, may be said to be of a well-known type or pattern andhas the usual ground and tapered body to give it a close fit in itsseatin coupling 0. Provision is also made to utilize this plug for Wastepurposes,as in stop and waste cocks and the like, if desired, and forthis purpose the said plug has an outlet-orifice 2, communicating withits central transverse passage-way 3. It will be observed likewise as afeature that the said orifice 2 is on a plane so far be low thewaste-outlet i in the coupling that even if the plug were turned aroundso as to bring the said orifice 2 to the front it could not thendischarge, because it would not be in a plane with the outlet 4, andhence it would be closed by the wall of the coupling.

Structurally and practically the plug A is novel in this, that it iscast wholly in one piece and has cast integral therewith what has cometo be known as a sand-cap 5 and a handle 6. The said cap is of a size incross-section adapted to somewhat snugly fit over and about the upperportion 7 of the plugseat, which is circular like a collar and stands upfrom or above the body of the coupling a suitable distance to enable cap5 to overlap the same and come down as a skirting, substantially asshown;

One of the most frequent objections met with in the use of a couplingand plug fashioned more or less like the one here shown is the dangerthat sand, dust, or dirt will settle in between the plug and its seat,and although these surfaces are ground so as to fit perfectly tight itstill is found that dust and sand will work into the bearings of theplug and scratch and mar the same and'sooner or later produce a leakycondition. Various precautions have been taken first audlast to obviatethis objection and protect the said bearing-surfaces from injuriousaccumulations from without, and I have accomplished this desirableresult by casting cap 5 integral with or upon the plug itself and makingthe cap of such depth as to extend down over the side of theplug-bearing collar 7 a sufficient distance and with such closeness asto prevent the creeping of sand or dust into the space within. Obviouslythere can be no accumulations from above, as before, because the cap iswhole with the plug, and as the cap fits closely about collar 7dirt isexcluded here also.

In practical use the plug is supposed to be set in a given relation tothe coupling 0 according as a right or left hand seating thereof isdesired, and this depends on the location of the plug and the couplingin the pipe connections. (Not shown.) The position of the plug in thecoupling is further determined by screw D, which is shown here as beingontered through cap 5 into the body of the plug between the top ofbearing extension 7 and the top of cap 5 and serves as a stop for therotation of the plug against either of the quarter segments or lugs 9 onthe top of the coupling. Between these segments or lugs there are alsosegmental recesses 10 and 12 of quarter-size, and the position of theplug for right or left uses is determined by bringing screw D to playeither in the recess 10 or recess 12,

according as a right or left hand position ofthe plug is wanted. By thisconstruction the plug is kept absolutely clean and is adapted to servefor an indefinite period in the most exposed places, as beneath cars andlike places where there is much dust. Then it possesses thefurtheradvantage of carryingits own handle as an integral part, and thisis made possible by reason of casting the cap on the plug. If it werenot so cast and had to be slipped down over the plug, a separate handlewould be required. As it is, the plug is a complete and self-containedarticle carrying its own equipment and being ready for use and to beoperated without bringing anything to it for this purpose. Any suitablestyle of handle can be used.

What I claim is- 1. A plugfor steam and water cocks having a cap castabout the top portion thereof and a removable stop Within said cap, incombination with a coupling having a seat for said plug and a projectionon said coupling in position to be engaged by said stop, substantiallyas described. l

2. In Water and steam cocks,a coupling having a seat with a circularupper portion projecting above the body of the coupling and lugs on thetop thereof,.in combination with a plug having an integral cap about itstop encircling the said upper portion of the seat, and a removable stopin said cap to engage said lugs, substantially as described.

3. The coupling having a seat for a plug provided with a circularextension about its top and lugs on the top of said extension, incombination with a plug having a cap integral with itsupper portion andinclosing said lugs and circular extension from above, and a removablestop in the cap arranged to engage against said lugs when the plug isrotated, substantially as described.

4. As a new article of manufacture, a plug for water and steam cockshaving a tapered barrel and a cap and handle castintegral with its upperportion, said barrel having a fluidpassage through its center and a holethrough its cap for the insertion of a stop, substantially as described.

Witness my hand to the foregoing specifi-- cation this 23d day of July,1901.
